Dumbass what was regarded as “White American” was very subjective for the entire history of this nation, in fact, “White American” as a reference to anyone European American is a fairly new development, as back in the 1800s one is only regarded as “white” by certain elements of the racist white community if you belong to a specific group of European, IE the so-called “Anglo-Saxons” or rather English or Scottish but eventually expanded to other groups but frequently being forced to, since they used to discrimination against Germans, Italians, and especially Irish.
if you fuckers ever got your way, that will become a thing again and you’d go Surprised Pikachu face when the very group you considered yourself a part of start to call YOU nonwhite because of the specific European ethnic group you were apart of, which shouldn’t surprise anyone given how violent European history is and how racist Europeans can get to each other not just non-Europeans but it's always a surprise to modern white supremacists.
